SAMUEL IB.-SHELDON, {0F DULUTH, MINNESOTA.

.GAS-PRODUCER.

- Be it known that I, SAMUEL B. SHELDON, a citizen of the UnitedStates,and resident of Duluth, in the county of St. Louis and State 'ofMinnesota, have invented certain new and useful ImprovementsinGas-Producers, of which the following is a specification. 4

This invention relates to gas-producers. One of the objects of thisinvention is to simplify and improve means for disturbing the fuel inthe coking zone for maintaining condition.

-- Another object is to improve the fuel pokers and the means foractuating the same.

Another object is to provide a gas producer having cooperative partsarranged to meet all the requirements for successful operation.

These and other objects are accomplished I by means of'the arrangementdisclosedby the, accompanying sheets of drawings, in.

which Figure l is a plan view of my gas producer. Fig. 2 is afragmentary View of the upper part of the same, and

Fig. 3 is a vertical sectional view ofthe fuel feed and-distributingarrangement.

The various novel features of my 'inven tion will be apparent from thefollowing description and drawin s andwill be particu-' larly pointedout in e appended claims.

In view of the fact that my inventionrelates to mechanism mounted on thetopjof the gas producer, only the upper part of the gas producer isshown.

The main body portion 1O of the gas producer has at its upper end achannel portion 11 in which the vertical flange 12 of the rotating top13 moves. The top and the v parts mounted thereon are all actuatedthrough suitable mechanism by an electric motorl l, the shaft of-whichis provided with the pinion 15, meshing with a gear 16 mount ed on ashaft connected to suitable gearing ,within a gear "housing 17.Extending outward from this housing is a shaft 17 carrying a pinion 18,.which meshes with and drives a" relatively large gear 19, mounted upona shaft '20 to the outer end ofwhich issecured'a traction wheel 21bearin u'ponthe stationary body portion 10 -o the gas producer, wherebythe top of the gas producer is rotated. Secured Specification of LettersPatent. Patented Aug, 24, Application filed June 11, 1918. Serial No.239,361.-

By means of this eccentric drive arrange vertical sectional the pokershown-at the right of the center of the gas producer. By means of thisarran ement the outer annular portion of the b. including tl i at inthe'coking zone, being dis the top..

to theother end'of the shaft 17 is an eccentrlc 22 (see Fig. 2)ope'ratively connected to a yoke member 23 secured to a shaft 24 uponwhich a walking beam 25 is. mounted.

ment the opposite ends of the walking beam 25.are given a rising andfalling movement.

- Secured to each-end of thewalkin beam 25 is'a ball socket 26 in whichis movab y mount- 'ed'a-ball 27, the latter of which maybe in asinglepiece for in a plurality of pieces.

Extending upwardly from the ball 27 is a tubular portion 28 andextending downwardly vfro' m the ball 27 is another tubular portion 29,there being an opening through the mam part of the ball 27 registeringwith the opening in the tubular portions 28 and 29. Extending throughthese openings is a thzgeaded portion on a shank 30 of the poker.

The lower end of the poker is not shown,

' but it will be understood that the poker per- The ball and socketjoint for thep'oker is the same -at each end of the walkingbeamh In.

poker to the left of the centerof the walking beam, as shown in Fig. 2,is located farther fromthe center of the gas producer than is.

fue -'bed is disturbed by the outer poker and the inner annula-r portion.of the fuel bed is; disturbed the inner poker, all' f the fuel,-

turbed during one complete revolution of By means of theball and socketjoint con-.

nection between the'wa'lkingbeam 25 and-100 V the shanks ofthe pokers,the pokers are free to drag a certain amount as 'the top of'the gasproduceris rotated and at the same time the poker is free to move in aline coincident movement of the walking beam 25. As shown, the walkingbeam 25.-is in central positioirf Let it". be assumed," however, thatthe actuating shaft 17' is moving in a clockwise direction, as viewed inig; 2. Accord- 110 with or parallel to? the vertical plane of;

. 35 a this connection it will be noted that the j same uniformlyporous.

ingly, the one arm of the walking beam will be depressed and the other.arm of the walking beam will be raised. In view of the fact that theconnection between the walking beam and the poker is more clearly shownwalking beam 25, the poker follows the beam but falls as a result of itsown weight,

and regardless of the extent of downward .movement of the arm of thewalking beam, the poker will extend into the-fuel bed only an amount inaccordance with its own weight. Inactual operation, when the end of,thearm of the walking beam is in its lowermostposition, the nut M of thepoker shank 30 may be out of engagement with the upper eiidof thetubular portion 28 of the ball ii'fl Thisis due to the fact that thefuel has offered resistance to the downward movement of the poker to-theextent that the latter was not able ofits own weight to follow thewalking beam forits full throw. If. however. it is desired that thepoker should be positively thrust down int-o the fuel bed for breakingthe same down or for any other reason, the walking beam 25 and theshank30 of each of the pokers may be positively connectedby link orclevis means 33' parts of which may extend through openings .32 and inthe tubular member 28 and the nut 31. respectively. g

It will he understood that the top 13 of the gas producer revolvescontinuously and at a relatively slow rate. Asa result thereof, duringthe up and down movement of the pokers while they are inthe fuel'bed,the bottom of each of the pokers is caused to lag a certainpredetermined amount thereby pressing the portion of fuel being.pQ-litttl circumferentially in advance of the poker a slight amount.This action takes place throughout the whole revolution,

' thereby treating all parts of the coking zone of' tlie fuel bed thesame and rendering the It is to be understood that'the oppositely actingpokers are raised above the fuel."then move vertically down into thefuel and while still in the 'fuel bed laga given amount beforethey areraised out of the fuel as the top of the producer rotates By adjustingthe nuts 31 on the shank 30 of each of the pokers. the ver-' ticalmo'yementof the latter into the coking zone maybe varied.

The shank 3d of each of the pokers is hollow. whereby a cooling medium.such as ivater, may be supplied thereto through a suitable supplyconnection 3-]: and from which the excess amount of cooling fluid maypass through an overflow connection 35. Secured to the lower tubularportion :29 of the ball 27 is a skirt 36 extending down into an annularchannel member 37, secured to the top 13 of the. gas producer, whereby awater seal is formed to prevent the'escape of producer gas through theopening 38 through which the poker shank 30 extends. 1

Mounted on the top 13 of the gas producer is a fuel-hopper-39 whichreceives its supply of fuel through a chute t0, the upper end of whichis in register with the supply opening 4:1 of a coal bin l2. As shown,the outlet 41 is arranged concentrically with respect to the gasproducer and the fuel hopper 39 arranged eccentrically with respect tothe center of the gas producer. the chute it) accordingly being arrangedat an angle. It will be appreciated.however, that these parts may bearranged in accordance with requirements While I am claiming'the coalfeed and distributing arrangement in a co-pending application. I willdescribe in a general way in this'application. the general arrangementofthe parts. a The coal hopper 39 preferably is divided into twocompartments l3 and H. separated by a central wall +5. Mounted in eachof said compartments l3 and ell for reciprocation therein is a plungerl6 operatively connected to an arm i7 keyed to a shaft-l8 to which isconnected an arm 49, connected in turn to a rod 50, one end of which isconnected to a shaft 51, through an eccentric 52, whereby each of theplungers i6 is reciprocated. It will be understoodthateach of theplungers has its own reciprocating mechanism, the latter in each casebeing operatively connected to the shaft 5l,"to one end of which issecured a gear 53 which is driven by gear 19. Fuel from the hopper 39flows downwardly in frontof the plungers 6, the fuelsloping off infrontof the plungers at an angle of repose. The fuel in front of theoppositely actuated plungers 46 is pushed onto. a distributer 5i, whichis eccentrically arranged with respect to the vertical 61 to fo'rm awater seal inthe annular chan- Y nel members 62. -The floor 63 of thehopper 39 is water cooled as is also the partition or wall i5 betweenthe compartments 4:3 and H.-

The top 13 of the gas producer is cooled ing circumferentially arrangedopenings 65 a by forcing formed therein by an annular wall 64 havthroughwhich the water may flow radially outward over the upper surface .of thetop for cooling the latter. The excess amount of cooling water suppliedin this way may overflow the sides of the gas producer;

There may be various modifications of .my

.invention, as herein particularly, shown and described and it s myintention to cover all one direction and moves in asuchmodificationswhich do not involve a departure from the spirit andscope of the invention, as set forth in the following claims.

I claim:

1. In a gas producer, the combination of a walking beam,-and pokersmounted on op-y posite sides of the center thereof I for disturbing thefuel in the coking zone;

2. In a gas producer, the combination of a walking beam mountedfor'rotation and having arms of different lengths, and pokers mountedthereon at different distances from the center, having different pathsof movement. r

3. In a gas producer,the combination of a walking beam, anda pokerhaving an up and down movement and connected to the walking beam by aball and socket joint whereby the poker may have freedom of movementin-a plurality of directions.

4. In a gas producer, the combination of a walking beam, eccentric meansfor actuating said walking beam, and apoker mounted on .water into 'acentral chamber said beam for disturbing the fuel in the coking zone. 1I

5. In a gas producer, the combination of an actuating member, and apoker having an up and down movement and connected to the actuatingmember/by a ball and socketjoint whereby the poker may have freedom ofmovementin a plurality of directions. 6. In a gas producer, thecombination of a walking beam, a poker connected thereto whereby thepoker is positively moved in difierent direction .under the influence ofits own weight, and means whereby the poker.may be positively actuatedinsaid different direction.

7. In a gas producer, the combination of a lifting member, and a pokerslidably connected thereto whereby the latter in its downward movementfollows the actuating member under the influence of its own weight andcontinues, until it is stopped by the resistance of the fuel bed orby-the actuating member.

8. In'a gas'producer, the combination of a rotary top, a walking beammounted thereon, and pokers connected to said walking beam whereby thepokers travel for disturb-' in fuel in a circular path. I
